原题:on a purchase of $120, a store offered a payment plan consisting of a $20 down payments of $10 each. What percent of the purchase price, to the nearest tenth of a percent, did the customer pay in interest by using this plan?
答案是16.7%
看不懂what percent 后面什么意思?什么nearest tenth of a percent?
如果是保留小数位的话是否需要四舍五入呢?

to the nearest tenth of a percent是指精确到小数点后一位 如:16.7%,17.8% etc.题目意思是买了个120块钱的东西 你首付20 每个月付10块 问最后这个顾客选择这种(按揭)方法购买商品付出的利息/商品原价,即→利息=20+10*12-120(原价)=20 ,利息/原价=20/120=1/6精确到小数点后一位,即为16.7%.
就是让你小数点后保留一位有效数字
nearest tenth of a percent? 百分号前面约简到十分位。
